JOSEPH w. NETnEnYI, or INDANAroLIs, INDIANA, AssieNoP. 'ro NETHERY VALVE eOMPANY, OF AUGUSTA, MAINE, A CORPORATION or MAINE.

Be it known that I, JOSEPH a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and -useful Improvements in Faucets, of which the following is a specification.

My present invention relates especially to that .class Of'valves Or faucetswhich are employed in drawing limitedquantities of water,

` as for domestic use, and in which it is desired .to limit the quantity of the dischargeautomatically. y

The accompanying drawings illustrate a faucet (such as is commonly used in connection with a wash basin)k embodying my said invention.

Figure 1 is a side elevation; Fig. 2 a cuen- 4tral vertical section of the saine when the' valve is closed o r seated; Fig. 3 a view simi'- lar to Fig. 2, except that the valve is pushed downwardly to the limit` of its movement,.

and Figyl a detail horizontal sectional view at the point indicated by the. dotted line 4 4 in Fig. 2.v` l

' In` Operation, the water comes-in from a suitable pipe through the lowertubular portion 21 of my im roved faucet, vand its tendency is to hold t e valve 22 against its seat 23.v Said seat is preferably a, disk of leather or other suitable material 23, and is secured `to the lower end of the shell'24 of a suitable cylindrical retarding chamber. Said valve 22 is mounted on a valve stem 25, and said valve stem carries a piston head 26 which is positioned within the retarding chamber. Ihe valve stem extends up through the faucet Vto the outside, and bears on its upper end a push button 27 by means of which the valve is opened. A stuffing-box 28 is provided in the structure (just above the retarding chamber)`and serves the usual purpose of a stutling-box to prevent leakage, etc. \The stalling-box capis embodied ina structure 29 which is provided with a grip 30 by which it Ais manipulated. Within the upper por Ation of this structure 29 and within tic lower side of the push button 27 I prefer to form a c lindrical chamber, as shown, and in this c ianiber I preferably )lace a compression spring 31. In cases where the water pressure is strong, this spring is unnecessary; as the ressure of the water on the valve 22 will itso f force said valve back toward its seat aty the proper speed, but where the pressure is Specific-ation of Letters Patent. Application filed July 21, 1905. Serial No. 270,689.

low this spring is desirable as an auxiliary to said waterpress'ure in closing the valve.

The compression chamber' before referred to serves' to retard the ,movement of the valve as it closes. The piston head 26 fits vclosely within the Wall 24 of .said chamber, although it is not erfeotly water tight. As the valve is opener (by pressing down on the button or cap 27) water Will enter this chamber, which, at the termination of the stroke', is of the size indicated in Fig. 3. When pressure on the cap 27 is released the entire struc- ,ture will begin to ascend, and the assage of water out around thepiston head lieing necessarily slow the ascent of the valve is corre- .s ondingly slow. This may be adjusted, if

esired, but ordinarily the pro er result is attained bysimp'ly making a s ightly loose fit and iilling't-he annular rooves around the periphery of the piston ead, with wax or some similar' substance. I have found by `actual. test that this gives a'suliicientlyexact result for all ordinary practicalA purposes. The travel downwardly is limited by the piston head26 coming incontactwith the bottorn of the `chamber in which itv travels. I prefer to cushion the blow occasioned by this contact, andfor that reasonprovide acollar 32 on the valve stem 25 just below the )iston head 26 of 4a diameter which will su stanltially fill the valve orifice, as is best shown in Fig. 3. Asthis collar enters said oriceit confines a small uantity of water between the lower side of t e piston head and the upper surface of the lower end of the chamber, which watcrforms the cushion in question, and revents. actual forcible contact of the meta Perforations il are formed in thewalLQllof .the chamber, and these are a part of the pase e valve orifice around the valve l through which the water will freely pass until the valve ,22 has seatedjitself a ainst the valve seat 23. The valve stem` elow the piston head is preferably of a: ta ered form, "icing larger at thepoint where t.. e valve 22 valveand valve seat removable structure.

is attached than it is where it leads the is t0n head 26. The result is'that the ow through the valve orifice through which said stem passes is gradually reduced as the Valve ascends until 1t is nearly closed at the time the valve-reaches its seat. This prevents hammering, as it is termed, and 1s a very desirable feature.

It will be observed that in this faucet the A nut 43 is formed on the part which embodies the retarding-chamber and the smiling-box, and said part just below said vnut Escrow-threaded into the body 44 of the faucet, so that by uns'crewing thesame by means of said nut all the operatve parts'rnay be taken out for repairing, cleansmg, or renewal, without disturbing the faucet body at all. T hose removable structures can be kept in stock and sold separately, so that the owner of one of these faucets, in case it gets out `of order, may pur- Chase the saine and thus be able to renew his valve (so far' as its working parts are concerned) at small expense, and without calling upon a plumber. i

Having thus fully described m said in Vention, what I claim as new, anni7 desire to secure by Letters Patent, is,- l

1. The combination of a valve stem, a Valve on the lower'cnd of said stem, a push on the up er end of said stem, a retarding chamber t u'ough which the Valve stern passes, a piston head on said Valve stein within said reare both embodied in a' l l l tardin chamber tarding chamber, and a valve seat at the lower end of said retarding chamber to receive either the Valve or the piston.

2. The combination of a body, a removable structure mounted in said bodyand embodying the valve seat at its lower end, and a reabove said Valve seat'havlng or' ees in the Walls ofsaid chamber somewhat above the Valve seat, and a' ried by the Valve stein and operating in said chamber to a oint below said orifices.

3. The combination of a body, a structure carried thereby embodying the valve seat and also a'retarding4 chamber, a valve stem mounted in said structurel, a valve on one end of said stem, a push button on the other end of said stem, said chamber being provided with orifices in its sides near the lower end, and a iston also carried by the 'valve stem and adiiptcd to travel in said chamber to a point below the valve is first operated the discharge orificos are rst shut oi and then gradually opened as the piston head ascends thereby causing a gradual How at the -beginning'and'a more rapid flow thereafter.

In witness whereof, I, have hereunto set my hand and seal at Indianapolis, indiana, this nineteenth day oi July, A. D. one thousand nine hundred and live.
